Understanding the RAW File: The Foundation of Every Great Edit
(Foundational Tutorial Series — Lesson 1)
When I first started learning photography, I didn’t give much thought to file formats. I’d shoot in JPEG because it was easy — the files looked good right out of the camera and didn’t take up much space. It wasn’t until I began editing that I realized how limited JPEGs really are.
If you’ve ever tried to brighten a shadow or recover blown highlights in a JPEG and ended up with muddy tones or weird color shifts, you’ve already seen the problem. That’s where RAW files come in. They’re the digital equivalent of a film negative — full of potential, waiting to be developed.
This post is part of a foundational tutorial series designed to help you understand the basics of photo editing from the ground up. It’s not meant to be a deep dive into advanced techniques or complex workflows. Instead, think of it as a solid starting point — something you can build upon through practice, experimentation, and time behind the camera.
By the end of this series, you’ll have a clear understanding of the tools and concepts that form the backbone of every great edit, no matter what style or genre of photography you pursue.
What Is a RAW File?
A RAW file is exactly what it sounds like: raw, unprocessed image data captured directly from your camera’s sensor. Unlike a JPEG, which compresses and bakes in color, contrast, and sharpening, a RAW file preserves everything your sensor recorded — giving you full control in post-processing.
Think of it this way:
- JPEGs are like finished meals. You can season them a little more, but you can’t un-cook them.
- RAW files are like fresh ingredients. You can shape the final result however you want.
Every camera brand uses its own RAW format (e.g., .NEF for Nikon, .CR3 for Canon, .RAF for Fuji), but they all serve the same purpose — maximum editing flexibility.
Why Shooting RAW Matters
Here’s what makes RAW worth it, especially for landscape and nature photography:
- Dynamic Range – You can recover details in both bright skies and dark shadows that JPEGs lose forever.
- Color Depth – RAW files often store 12 to 14 bits of color data per channel, compared to JPEG’s 8. That’s billions of possible color variations instead of just millions.
- White Balance Control – Adjust it freely after the fact without ruining the image.
- Non-Destructive Editing – RAW files never change. Your edits are saved as separate instructions, so you can always start over.
The tradeoff? Larger file sizes. But in today’s world of cheap storage and fast computers, that’s a small price to pay for full creative control.
When to Use RAW vs. JPEG
There are rare times JPEGs still make sense — like quick snapshots or event coverage where speed matters more than flexibility.
For anything artistic, deliberate, or landscape-related, though, RAW is the way to go. If your camera offers a “RAW + JPEG” mode, that’s a great way to have quick previews while keeping your full-quality files for later editing.
RAW Files and Editing Software
To unlock a RAW file’s potential, you need software that understands it. Programs like Adobe Lightroom, Capture One, or DxO PhotoLab interpret the sensor data and let you apply adjustments without altering the original file.
In this series, I’ll focus on Lightroom Classic, since it’s one of the most popular and powerful tools for managing and editing RAW files.
Common Misconceptions
A few things I wish I’d known early on:
- RAWs don’t look better out of camera. In fact, they often look worse at first — flat and low contrast — because no in-camera processing has been applied.
- RAW files need post-processing. That’s not optional; it’s part of the process.
- Shooting RAW doesn’t fix exposure mistakes. It helps recover detail, but it’s not a magic button for bad technique.
My Workflow Tip
I always shoot in RAW and import directly into Lightroom. Before I start editing, I apply a base preset that sets lens corrections, a slight tone curve, and color profile — essentially giving me a starting point. Think of this as the digital version of your “film stock.”
If you’re new to RAW editing, I recommend creating your own simple base preset after a few sessions. You’ll thank yourself later when you can start every edit on solid footing.

In the next lesson, we’ll dive into setting up Lightroom for the first time — from organizing catalogs to importing photos efficiently. Once your digital darkroom is set up right, editing becomes much smoother.
